steam from any suitable source. A branch In the method for extracting dyes, just described, the operation goes on continuously, or, in other words, the extractors are both charged and emptied successively. It is therefore quite apparent that in the proper operation of i the system each of the extractors should be capable of being isolated from the others While being charged, heated, or emptied, and this may be accomplished by a proper adjustment of the cocks, as will be readily understood. I

I will now proceed to a description of that portion of the apparatus which constitutes my invention; It will be observed that the pipes D of which I have illustrated one in dotted outline in Fig. 2, are bent so as to extend upwardly within the extractors. At the upwardly-extendin g ends of these pipeslplace valve-seats and winged puppet-valves J, of whichI have shown one more clearly in Fig. 3. Said valves are held in a vertical position by means of an upwardly-extending guide-stem passing through an opening in a frame-work extended from each valve-seat. By the use of these Valves all refiow of the liquid and chips from Within the extractors into the pipes D B B or B owing to ebullition within the extractors or other cause, is positively and automaticallyprevented. Heretofore in order I to prevent such reflow it has been necessary to manipulate the valves A when the extractors were being charged with water and again when such charge has been completed, and also when steam-pressure was being applied and when it was discontinued. These valves A, being high up and out of ordinary reach, have therefore caused much waste of time in their rmanipulation. They were also being constantly fouled by chips from the extractors, rendering their operation difficult and necessitating frequent cleaning and repairs, all of which is avoided by the use of my improvement. By my improvement, also, the continuous operation of the system is materially facilitated.

VVhatI claim as my invention, and desire to secure by Letters Patent, is

The combination, with an extractor constructed to be charged from the top and a tractor, substantially as specified.

THOMAS SCULLY.
